Creating J2EE 1.4 Applications in SAP NetWeaver Developer Studio
In the Java EE perspective of the Developer Studio you can create new or maintain and enhance existing J2EE 1.4 applications. This documentation focuses on explaining the specific configuration settings of the projects in your workspace rather than discussing the J2EE 1.4 development model.
You develop each J2EE 1.4 component in the corresponding J2EE 1.4 compliant project. For example, you develop EJB 2.1 components in a J2EE 1.4 compliant EJB project. You manage the specification version compliancy of projects using their project facets.
You can add J2EE 1.4 compliant projects to Java EE 5 compliant Enterprise Application projects.
If you need to create J2EE 1.4 components as part of Java EE 5 compliant projects, you have to do this manually. You cannot use the corresponding J2EE 1.4 component wizards.
The tasks of an application developer are grouped in the following main categories:
-
Creating Web components which usually comprise JSPs or servlets.
For more information, see Creating J2EE 1.4-compliant Web Components .
-
Creating EJB components that contain the business logic of your application.
For more information, see Creating EJB 2.1 Components .
-
Creating enterprise applications. You have to assemble all JARs and WARs in an EAR, which is represented in the Developer Studio by the Enterprise Application project.
